HEEL-LASTIN G MACHINE.

Application filed February 29, 1912.

To all whom it may concern:

Be it known that I, ARTHUR L. RtrssnLL, a citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Heel-Lasting Machines, of which the following description, in connection with the accompanying draw ings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of shoes and is embodied in a machine for assembling shoes and lasting the heel seat portions 0 the shoes.

An important feature of this invention consists in a novel organization of shoe assembling and shaping apparatus. Shoe upper materials require to be properly arranged relatively upon a last and to be maintained in correctly adjusted relation while being shaped to the last.

It is one object of this invention to combine suitable devices and mechanisms by which assembling and subsequent shaping and securing operations can be carried on expeditiously, without loss of adjustment, preferably with one handling of the shoe, and with such 0 portunity for the exercise of skill and judgment on the part of the operator in dealing with each shoe as is desirable for the best shoe making results.

Another feature of the invention consists in an improved shoe assembling jack. The jack is herein shown as employed to support a last and shoe materials while said materials are being arranged and to tension and hold the upper in position for shaping operations upon the heel ortion ofthe shoe. The jack shown is there ore provided with a last holder and with a gripper by the aid of which the upper can be tensioned. The

gripper is preferably so constructed and ar- Specification of Letters Patent.

tion consists in novel means for shaping upper materials to the side faces of the last. This 15 shown as embodied in tools constructed and arranged to engage opposite sides of the heel portion of a shoe and advance in contact with the upper materials from the rear portion of the heel toward the shank in a way to conform said materials to the contour of the side faces of the last. Preferably there is combined with said tools means for clamping the materials about the heel portion of the last. As shown the upper tensioning means cooperates with the shaping means by holding the upper under tension for the action of the shaping means. The shaping means may advantageously be carried by the jack.

Another feature of this invention consists in a novel heel seat forming mechanism. This mechanism is shown as comprising a power driven shaping roll and manually operated devices for controlling the pressure of the roll and for tilting the roll to vary the pressure upon opposite edges of the heel seat. Means is also provided for advancing and retracting the roll over the heel seat, and for holding the jack against displacement by any of the movements of the roll.

A further feature of the invention consists in the combination with upper shaping mechanism such, for example, as heel seat forming means and means operating to shape the upper to the side faces of the last, or either of such means, of a tacker and a jack movable to carry the shoe from the field of operation of the shaping mechanism into the field of operation of the tacker. In the drawings the jack upon which the shoe is assembled and the upper is tensioned is confined in a three station guide in which it has freedom of movement during the assembling operation, is maintained rigid against de pression and against movement lengthwise of the shoe in the field of operation of the seat shaping roll, and is held yieldingly upraised and permitted turning movement in the field of operation of the tucker.

These and other important features of the invention, together with certain combinations of parts and useful details of construction will appear more fully from the following description of the illust ated embodiment of the invention and will then be po nted out in the claims.

'l he machine comprises the post which supports all the operating parts including the spindle l which rests by its bail end in a spring seat 5 in a pocket near the base of the post. The spindle is confined within a triangular loop 6 projecting from the side of the post and having three forks 7, 8 and 9 in the latter of winch the spindle rests normally by gravity in a forwardly tipped position. A collar 10 is threaded upon the spindle to rest on the top face of the loop when the spindle is in any one of the forks and give vertical rigidity to the spindle. A hand wheel 12 also threaded upon the spindle gives adjustable support for the jack whch includes the bar 15 and lever 16 on the rear side thereof. The bar 15 has a last pin 18 adjustable in its upper end by a partially inelosed nut 19 and has a forwardly extending arm 20 that is forked and between the sides of which slides a pincer. The pincer comprises inner and outer jaws 24:, 25 the former of which forms the toe rest for the last and is curved and extended laterally into crescent shape conforming to the contour of the last in cross section at the tip line of the upper as shown in Figs. 1, 2 and 7. The outer jaw is of similar shape and constitutes a gage by which to position the tip seam of the upper angularly with relation to the median longitudinal axis of the last before the upper is tensioned or in any way fastened, and while therefore it is freely shiftable into correct position.

The outer gripper jaw 25 is fast on the carriage which slides between the forks of the arm 20 and has an upper guide member 26 and a lower guide member 28. The

, inner jaw is formed on a lever 30 which extends upwardly and forwardly from the jaw within the upper and thence downwardly and backwardly, as shown in the drawings, to its fulcrum 32 in the lower guide member 28. \Vith the lower end of the lever 30 is connected a chain 35 which extends upwardly over a pulley in the guide member 28 to a pulley in the guide member 26 and thence over an idler in the front end the operation of conforming of the arm 20 and downwardly where it is connected by spring 36 to a gripper oper' ating lever 40. This lever is pivoted to the bar 15 and has a pawl 38 to engage a segment ratchet on the bar for locking the lever e0 depressed with the upper seized and pulled and held under tension of the spring 36. A pawl lifter 39 provides for conveniently releasing pawl 38. A pawl 42! pivoted on the lower end of. jaw lever 30 engages a ratchet 43 in gu.de member 28 to lock the jaws closed even when the lever is released, as for example, to readjust the upper on the last, and a tripper ll on arm 20 will disengage pawl 42 when the gripper is allowed to slide down the inclined arm 20 or release can be etl'ected manually by finger pressure on the pawl l2.

'1 he lever 16 which is pivoted to the jack bar 15 has a forwardly extending ear in a bearing in which turns a rock shaft having a hand lever 50. From this shaft depends an arm 52, Fig. 2, with a roll in a slot in the bar 15 arranged to cause downward pressure on the hand lever to draw the lever 16 and parts supported by it toward the shoe. A pawl 54: engages a ratchet face on the link to lock the lever 16 against backward movement. The head of lever 16 has a forwardly projecting lug to which forwardly extending curved arms 55 are piv otally connected. These arms carry the devices for conforming the upper materials to the side faces of the heel part of the last, including the forming tools and the clamp 62. arms 55 are formed to afford bearings for a vertical axle rod 64. upon which the tools 60 are mounted to roll, said axle rod being smaller than the holes in the rolls as appears in Figs. 4, 5 and 6. The arms also have guide bearings for spring pressed plungers 65, one for each roll, the heads of which, Figs. 5 and 6, are held by the springs against the rolls to press the latter toward the shoe to the limit of the movement permitted by the difference in diameter of the rod 64 and the axle hole in the rolls. The heads of the plungers, Fig. 6, are long enough to allow the rolls to roll along them from the front to the rear as the rolls do their work. The rolls may be inelosed within a cover strap or apron 68 as in Fig. 5 which will present a continuous shoe engaging surface covering the lines between the rolls as the latter yield independently of one another as indicated in Fig. 6 to conform to the contour of the side face of the shoe. The arms 55 are pressed toward each other to cause the rolls to engage the shoe by the action of the spring plunger-s 69, Figs. 2, 3 and 4, which are carried by the head of lever 16 and abut against depending lips 58 of the arms as appears best in Fig. 2. In the use of these conforming tools the hand To this end the free ends of the lever 50 is manipulated to bring the lever 16 forwardly and the tools into engagement with the rear end portion of the heel and lever 50 is then vibrated to cause the rolls 60 to roll forwardly and then backwardly along the sides of the shoe as indicated by the arrows, Fig. 6, and to progress as they vibrate. In this way the stock is rolled repeatedly along the side faces of the heel to conform the upper and the heel stiffener to the contour of the underlying face of the last as the rolls yield independently of one another. Also as the operation progresses forwardly by reason of longer forward than rearward vibrations the rolls drag a little at a time, as hereinafter explained, and by their rubbing action on the upper pullthe upper forwardly to tension it around the heel end of the shoe.

The arms 55 carry the edge clamp 62 by means of swinging bars 70, and said clamp, which comprises a steel band with a cushion lining, is resilient enough to maintain itself normally open and drawn forwardly. As the parts are moved forwardly the clamp is caused to embrace the shoe with its ends lightly following the rolls 60 as the latter reach the shank whereupon the rear end of the clamp engages the rear end of the heel which interrupts its 'further advance. As the lever 16 continues to advance the clamp is tightly clamped about the heel at its edge, and being narrow, the pressure of the clamp is concentrated at and just below the edge of the heel where it is most effective, while further advance of lever 16 reacts through swinging bars to separate the free ends of arms 55 as in Fig. 4 and carry the rolls 60 out of contact with the shoe. In this operation the spring plungers 69 are pressed back as may be seen by comparison of Figs. 3 and 4. These plungers have headed tail rods 74 and upon these heads rests normally a bar 75 that is mounted by arms 76 to swing about a rod 77. As the heads are forced backwardly the bar 75 drops in front of them and locks the plungers with the arms 55 apart and the conforming tools 60 out of contact with the shoe for the backward movement of lever 16 when the shoe is released. This avoids any drag of the rolls rearwardly over the work. A rod 78, Fig. 2, is movable by a thumb iece 79 on a rock shaft to lift the bar 77 an free the plungers 69 and arms 55 for operation on the next shoe. The swinging bars 7 0 are guided over segment rails 72 on arms 55 to allow them to move easily. An adjustable stop 73 affords provision for preventing excessive forward movement of lever 16. The parts come to rest with the clamp 62 clasping the shoe firmly just below the plane of its bottom face to hold the heel stiffener from bulging away from the side of the last when the flange of it is bent down upon the heel seat. The clasp is also in position to cooperate with the heel seat forming means to shape the angular edge of the shoe where the side and bottom faces join.

The heel seat forming means is a roll 80 the acting face of which comprises two series of yielding heaters 82 extending obliquely inwardly from the opposite ends of the roll and backwardly with relation to the direction of rotation of the roll as will be understood from Fig. 1 and the plan or development of the roll seen in Fig. 8. This roll IS constructed under United States Letters Patent to Wentworth No. 896,873 and need not be here more particularly described. Herein the roll shaft is mounted in the forked front end of a carrier rod 85 that is movable endwise and also can tip slightly in a bracket 86. This bracket has in its inner edge a guideway by which it em braces a guide rib 88 on the side of the post 2. A spring of appropriate size upholds the bracket 86 against an adjustable limit stop 89 but permits it to be pulled down by a rod connected with a treadle 90 to cause the roll 80 to act with desired pressure upon the heel seat of the shoe, the jack occupying at this time the seat 8 in. loop 6. The roll shaft has at its inner end a pulley 92 engaged by a belt 94 which runs over idlers 95 carried by an arm extended from the belt carrier 85. From thence the roll runs to a continuously rotating pulley 96 loose on the power shaft of the machine. By arranging the pulley 92 and idlers 95 upon the carrier 85 the belt is maintained at substantially uniform tension in the different positions which the roll may occu y during its operation. A handled lever 100 is pivoted in a slot in the carrier rod 85 and its inner end is loosely fulcrumed between the side walls of an arc-shaped box 102. This mounting permits the roll and its carrier rod to be moved forwardly and backwardly for actuating the roll over the heel seat of the shoe and it also permits the roll and its carrier rod to be tipped about the longitudinal axis of said rod for positioning the roll with its axis parallel to the plane of the shoe bottom or for applying special pressure to one side or the other of the heel. By manipulating the lever 100 the constantly running heel seat forming roll 80 can be advanced and retracted over the shoe bottom, the pressure being regulated by the treadle lever 90. This treatment of the shoe by the seat forming roll is applied while the upper is held under forward tension to set it around the heel end of the last and the action of the roll is to draw the upper over the heel seat from opposite sides of the shoe simultaneously in lines which are directed obliquely forwardly and inwardly. The roll beats the upper down upon the heel seat progressively from the rear end toward the breast of the heel. Both sides of the heel seat are thus progressively shaped at the same time from the rear end forwardly by sliding blows directed inwardly and forwardly from opposite edges of the shoe bottom. The clasp 62 cooperates with the roll to shape the angular edge of the heel seat. When the heel seat has been satisfactorily formed and beaten until it is set in lasted condition the jack is moved into the seat 9 in loop 6 where the heel seat of the shoe is under the nozzle of the tacker.

The loose pulley 96 is continuously driven by a belt 105 and is mounted to slide on the shaft. A lever 106 pivoted to the head of the machine engages a collar on the pulley for effecting its sliding movements. A pull spring 108 connected to the upper end of the lever and to the head draws the lever in the direction to slide the loose pulley 96 into driving engagement with a clutch member 110 fast on the shaft. A horizontal lever 112 has its lower end underlying a shoulder on the lever 106 and has a block 113 to engage laterally against the lever 106 and turn it against the pull of spring 108 to slide the loose pulley 96 out of driving engagement with the clutch member 110. For disengaging said block 113 from lever 106 to permit the clutch to be closed and the tacker started the front end of the lever 112 is adapted to be lifted by a tripping device 115. This is shown in the form of a bell crank lever, a lower arm of which extends into position to be engaged by the side of the shoe, or by the clamp 62, and rocked when the shoe is pressed laterally against it. A horizontal arm of the bell crank actuates the lever 112 through an adjustable contact screw 116. While the tacker might be caused to run continuously as long as the shoe remains pressed against the tripper, the operator turning the shoe rapidly enough to space the tacks around the heel seat, provision is herein shown for stopping the machine after the insertion of each tack and requiring a renewed pressure against the tripping device before another tack is driven. To this end a lever 120 carries the fulcrum for the horizontal lever 112 and the upper end of this lever 120 has a roll in a cam path of a cam block 122. This cam path is formed to impart to the lever 120 and the horizontal lever 112 during each rotation of the machine a movement forwardly and then backwardly by which the block 113 of lever 112 is carried out from under the shoulder on lever 106 and then moved to the left again to abut against the slide of said lever 106 and swing the latter against the pull of spring 108 to slide the continuously running pulley 96 out of driving engagement with the clutch member 110.

The shaft has a cam 125 on its front end arranged to lift the driver bar 126 against the pressure of the driver spring 128. The driver cam is positioned to allow the driver to be forced downwardly by its spring immediately after the machine is started to insert through the nozzle 130 a tack which has been fed during a previous cycle of the machine. The tacks are fed from the magazine shown in Fig. 1 through a raceway to a separating mechanism which is not herein shown as these tack supplying devices form no part of the present invention. The -backer has a forked foot plate 132 against which the shoe is upheld by the spring 5 and under which the shoe is moved to engage the tripping device 115. The foot plate serves as a wiper during this movement and also serves to press the upper materials firmly down upon the insole for the reception of the tacks.

In the use of the machine a shoe comprising a last, innersole and upper materials, including the heel stiffener, is assembled upon the jack and there prepared for the heel seat lasting operation. It is contemplated that during this assembling operation the spindle will occupy the seat 7 in the loop 6, this seat being formed to hold the jack in stable condition with the shoe far enough away from the heel seat forming roll and the tacker to allow convenient access to all parts of the shoe. At the time the shoe'is applied to the jack the arms 55 will occupy their open position as illustrated in Fig. i and the clamp 62 will also be open and together with the arms 55 retracted from the shoe so as to be out of the operators way. This retraction of these parts is effected by releasing the pawl 54 and lifting the lever 50 whcreup on the lever 16 swings backwardly by gravity to an out-of-the-way position determined by the stop 73. It will be understood from the previous description that the bar 7 5 is the means for maintaining the arms 55 in open position against the pressure of the spring plungers 69. In applying the shoe to the jack the forepart of the upper 15 inserted between the open jaws 24, 25 of the toe gripper and the last rests down upon the inner jaw. The upper is positioned longitudinally about the last by locating the tip scam in symmetrical or other desired relation to the outer jaw of the grippers before the jaws are closed, the parts being so arranged that the operator can easily see the relation of the end portion of the tip seam to the end portions of the jaw on both sides of the shoe. A light pressure upon the lever 40 now eifects closin of the jaws to grip the upper and draw it orwardly under a light tension. The operator may now inspect the shoe to make certain that the heel portion Ill heel part of the last and more particularly 1 that the marginal portion of the upper and heel stiffener extend the desired distance above the plane of the insole to allow them to be lasted in correctly, that the ends of the heel stiffener are pulled up as they should be and that the back seam of the shoe is centrally located. If the latter condition should be found not to exist then the last can be turned upon the heel pin 18 to adjust it within the upper. Such turning movement of the last may also be effected after the upper has been further tensioned, so as to prevent it from slipping about the heel portion of the last, and by this means the last and the tip seam may be relatively positioned to bring the seam at the desired angle tothe longitudinal axis of the last. When the parts of the heel portion of the shoe are in proper relation the lever 40 will be depressed for stretching the upper forwardly and drawing it tight about the heel portion of the last. In this pulling operation, it will be noted that the upper at the two sides of the last is put under forward strain and that the direction of movement of the grippers on the guide arm 20 is such that the grippers are at all t'mes on the same side of the plane of the last bottom as is the top face of the last. that is, the grippers are below the plane of the inverted last at the end of the pulling operation and therefore there is no relaxation of the tension along the marginal port on of the upper such as would occur if grippers were operated to draw the upper over upon the insole at the toe. In the latter case such slackening of the marg nal portion of the upper would occur as would leave it loose around the edge of the heel portion of t ie last and render d flicult the accurate conformat on of the upper materials to the contour of the heel portion of the last. The lever 40 is locked in depressed condition by the pawl 38 so that the grippers are caused to main ain the upper in the described condit on during subsequent operations on the shoe. the spring 36 serving to give a yielding qualitv to the tension and to effect further movement of the grippers which may be perm tted by taking out additional stretch from the upper during the heel seat shaping operation. The devices for conforming the upper to the contour of the side faces of the last and further Working the upper forwardly about the heel portion of the last are now brought into operation. The lever 50 is actuated to bring the lever 16 and arms forwardly and when the formingtools are in proper relation to the end of the heel the tripping device 79 is depressed to raise bar 75 and allow the arms 55 to close for moving the tools 60 against the shoe. As these tools engage the shoe they are allowed by the spring plungers to move relatively to one another for adapting themselves to the contour of the engaged portion of the side of the last. The lever 50 may be now oscillated to move the arms 55 lengthwise of the shoe forwardly and backwardly to cause the tool 60 to conform the upper and heel stiffener to the contour of the side faces of the last by a rolling action. The forward movements will be longer than the rearward movements so as to carry on the operation progressiveley from the rear end of the heel forwardly toward the shank. Referring to Fig. 6, it will be understood that during the last part of each forward movement the plunger 65 and pin 64 offer considerable resistance to continue turning movements of the rolls and that the rolls are therefore caused to drag or rub forwardly thereby exerting a series of forward pulls as the operation progresses. If the apron or strap 68 is employed it forms a continuous surface covering the lines between adjacent rolls and the above mentioned forward pulling movements may be transmitted through it. As the shaping tools 60 approach the shank of the shoe the clamp 62 is drawn about the upper part of the shoe as will be understood from Figs. 3 and 4. The band adapts itself automatically to the shape and size of the shoe and when it has snuglv embraced the shoe and can move no fa ther it becomes a fulcrum for the swing ng bars 70 which then operates to separate the swinging arms 55 thereby withdrawing the rolls 60 from contact w th the shoe as shown in Fig. 4. In this latter mo ement the spring plungers 69 are compressed and their headed tail rods mo e under the bar unt l that bar can drop down in front of the heads on said rods where it will lock the plungers 69 against ad anc ng again. The pawl 54 will lock the le er 16 and the parts actuated therehv against re e se mo ement so that the elamo is caused to hold the upner curelv without further attent on. It Wlll be noted that this clamn is intended to engage the shoe for a short d stance onlv from its ed e down ardlv. It is the efo e substant allv unaflected hv var ations in the vertical curvature of the s de faces of different lasts and serves to hold t e heel st f-- fener securelv clasped about the last 111st below the edge line whe e the stiffener tepds to bulge outwardlv at the t me it is he'ng bent fo wardlv upon the inso e at the heel seat. The clam'o therehv cofinerates effectivelv with the heel seat fo m ng means to produce a close fit of the shoe stock to the last and to produce an angular edge of the lasted shoe as dist nguished from the rounded edge which there is alwavs a tendency to form when stifi material is bentover the angular edge of a last or other fo m. The shoe is now readv for movement of the ack from the seat' 7 to the seat 8 of the loop 6 for transferring the Work into the field of operation of the heel seat forming roll 80..

As the spindle of the jack enters the seat 8 the collar 10 thereof is caused to ride on to an inclined top face 81 of the seat for rigidly upholding the shoe for the heel seat lasting operation. The incline 81 takes the load and pressure intstead of allowing it to be received by the spring 5. It will be noted from Fig. 1 that the seat 8 is so formed in the loop that it holds the spindle against movemgnt forwardly and rearwardly and thereby securely resists displacement of the work in the direction which the movement of the heel seat forming roll over the shoe tends to displace it. The operator advances the continuously running roll 80 over the shoe by movement of the hand lever 100 thereby causing the two series of beating devices 82 to act simultaneously upon the marginal edge of the shoe upper materials for laying and beating them down upon the insole at opposite sides of the heel seat. The opposed angular arrangement of the two series of beating members with relation to their direction of rotation causes the roll to draw the upper over the heel seat from opposite sides simultaneously in lines directed obliquely forwardly and inwardly and beat it down upon the heel seat progressively from the rear end toward the breast of the heel. It is to be noted that this action takes place while the upper is under tension which pulls it forwardly to set it around the heel end of the last.

- The degree of downward pressure of the seat forming roll upon the work is controlled by the operator through the foot treadle and the hand lever ali'ords means by which the operator can tilt the roll 80 and bring it into parallelism with the heel seats of different shoes or can concentrate the forming action on one side or on the other side of the shoe. Experience has demonstrated that this heel seat forming operation will break down the upper materials upon the heel seat and draw them tightly into lasted position and set them in this position so that the shoe can then be taken to a tackin machine for tacking the heel seat. The ack is now shifted to the seat 9 in the loop 6, the top face of said seat being in a lower plane than the incline 81 so that the weight of the jack and shoe is sustained by the spring 5. The shoe is pressed laterally against the tripping device which through the mechanism above described causes a tack to be inserted. The operator turns the shoe to present the different tacking points under the nozzle. The lever and the cam 122 efi'ect stopping of the machine after the insertion of each tack and in pressing the shoe backwardly to cause tripping of the device 115 the shoe is caused to rub under the foot plate 132 which wipes over the upper materials and holds them down on the insole for the reception of the tack. When as many tacks as are required have been inserted in the heel seat, the jack is moved again to the seat 7. The pawl 5i and lever 50 are lifted to disengage the clamp 62 from the shoe and then the pawl 38 and lever (l0 are lifted and the grippers allowed to slide down the inclined guide arm 30 until the pawl 40 strikes the tripping device 4 whereupon the grippers are opened to permit the removal of the shoe from the machine. hen the shoe is taken from the machine it is in assembled condition ready for presentation to a pulling-over machine and the heel seat is completely lasted. Moreover, in the assembling operation, the upper may have been properly adjusted longitudinally about the last so that the shoe can be placed in the pullingover machine and the upper seized by the grippers with fair assurance that the tip seam will be properly located angularly and no tip straightening adjustment required during the upper pulling-over operation. It is contemplated that the longi tudinal stretch will have been taken out of the upper by the use of the described forepart "rippers so that the upper stretchins operation to be performed bv the pulling-0ver machine will be reduced and simplified. This is of particular advantage when shoes are being made upon lasts having high toes presenting a relatively low portion between the toe and the instep into which it is diflicult for the side grippers of the pulling-over machine to draw the upper down if the upper is required to be stretched by the toe gripper before the side grippers operate. Another advantage of this machine is that by seizing substantially the full width of the upper by the described toe grippers and stretchin the entire upper forwardly as herein explained, the shoe is more completely stretched than heretofore and it is possible to cut the shoe upper smaller than has heretofore been required, therebv ellecting a saving in upper stock. The operation of this machine also renders unnecessary the practice followed by many pulling-over machine operators of seizing the upper with hand pincers or with a tip puller and stretching the upper forwardly in order to draw the upper down the incline of the instep and otherwise position the upper lengthwise of the last so that the toe pincer of the machine can get hold of it.

I am aware of the invention of B. F. Mayo described in application for United States Letters Patent filed by him February 28, 1912, Serial No. 680.450, and I claim nothing that is disclosed in that application.
